Where are they and how can I use them?

Thanks - Andreas.

There are 2 bugs found, that runs to AV in multithreaded or interrupted by timer application.

First one in "module" procedure. Original algorithm dont fix possible buffer overrun.

Second one in "nrow, ncol" variables declaration. This variables must be declared in class, not as standalone unit shared variables.

Here is my suggestion with fixes.

I then created another template and let it inherit from the previous template. But when I open this new report it shows report title, then page header, then page footer.

How does one fix this?

So a while back I came across this video explaining how to add group totals to group header.

https://www.youtube.com/watch?v=TwmtT4rrvPM

At one point the uploader puts 2 OnbeforePrint events.

In the second event he writes the line

Set(<ADOQuery1."Company">, Sum(<ADOQuery1."ItemsTotal">, MasterData1));

The field <ADOQuery1."Company"> has the company name. Why are we suddenly giving it a new value? Or am I misunderstanding the above line?

In the first event he writes

Memo3.Text:='Sum:'+FloatToStr(Get(<ADOQuery1."Company">));

If Memo2 already contains the sum, why not just write Memo3.Text:=Memo2.Text?

i used FR 2026.1.6 with Rad Studio 12.2 Win64, everything worked fine.

After migration to Rad Studio 13.1 Win64x, first try with FR 2026.1.7 printing is working but runtime formular design brings Access Violation #0

Nothing had to be changed for migrating with FR use, no compile warning/hints.

Then i tried:

2026.1 is running

2026.1.1 is running

2026.1.2 and all above till current 2026.1.7 has the same issue with AV when trying runtime designer.

Are there any known problems with Win64x in that versions?

Regards,

Sascha

Is version 2026.3.1 compatible with D13.1? The issue also affects D12.2

Any advise to resolve this issue?

‘Memo24: Error in expression ‘My report title’: ‘;’’ expected’

Within my Delphi code, I’ve tried:

setting the report variable to my delphi variable

setting the report variable to my delphi variable surrounded with quotation marks (“)

setting the report variable to my dephi variable surrounded with apostrophes (‘).

But each variation generates the same error.  Of note: I created other variables in my delphi code that aren’t string types, and they seem to work fine, specifically TDateTime, Integer, Boolean. It’s only the string data type that’s causing problems.

When the Lazarus app is running, if you hover your mouse over that field inside the red box for just a few seconds, it throws an error.

I found that the problem happens whenever the width of that cell in the red box is smaller than the length of the text inside it.

MasterData
  Detail (Credits)
     Footer (Total Credits / Total + Last Day Total)
Mase
  Detail (Debits)
     Footer (Total Debits / Final Balance)

    
        
            

The final balance of the column is then used as the starting balance of the next column using like: (Except the first one, which gets its value from a Query on code)

[Memo22.Value] and the other day totals [Memo98.Value + Memo49.Value]

DoublePass is enabled, otherwise the first columns cannot access values calculated later in the report. Credits and Debits also come from different DataSets.

THE PROBLEM IS

The first two columns calculate correctly, but starting from the third column the starting balance becomes incorrect. The total value from day 12 is -4.424,15 but passing to the next day, the value become 4.914,55 positive, and i can't even find where that number come from...

I've also tried using BEFORE PRINT on the top Memos, but the result is the same. Any guidance on the correct way to carry calculated balances between columns? What could be the issue?

Thanks in advance!

But when I run the report the bar chart ends up empty. Am I doing it wrong or is this not possible?

Which is great. People can't edit them and poke around.

Due to another issue I have ( FieldDefs saved in FR3 when it didn't use to? — FastReport Forum )

I have to remove the password, save it as plain XML text, edit the file manually in notepad and leave it not encrypted do to the bug above.... ugh.

I have a modified version of the report editor program for my own use.

I don't have to input the password because I have this code, to set it.

frxReport1.ReportOptions.HiddenPassword  := 'bleh';

Which is great, don't have to hammer it in every time i edit a report.

The issue is, in the designer, you can't remove the password, IF, I have the above code to set the password.

If I remove that line of code, then I can remove the password.

So can see here, password is grayed out. I can't do anything.

Remove the 1 line of code, and rerun, now i can remove it!

uses 
..., FMX.Skia, ...
GlobalUseSkia := True;

But when you do that and call frxReport.DesignReport to show the report designer raise an exception "Invalid Printer class: TFakePrinterWin". 

But all go normal when omit the line "GlobalUseSkia := True" or comment. 

I post because spend a lot of time trying to solve it.

on my report, the MasterData band display only one field from my dataset, i use a TfrxMemoView as component.

It take the full band, align alClient, and can hold plain text of various sizes from one record to another, when having a large scale size text, it is splitte on 2 pages, as expected. The issue is on the second page printing, it occurs on the top of the page. How can i tell FR to print the second page at the same hight of the first one?

BR

Laurent

But instead, it is printing page 1 > page 1 > page 2 > page 2

This is the structure of my report. MasterData 1 and 3 uses the same dataset... does anyone know what could it be or what i could do to make it print the way i mentioned?

I've done some research, and this looks like to be in relation to the 'Collate' property that doesn't do anything, and that it is a problem old that existis since 2014 or less... but i couldn't find anything to correct this other than "use only ONE page". But i need both pages

I'm new with FasReport . I have build an app with XE2 CPP for analyzing soms analog signals.

The result must be into a pdf report. I saw that there are two ways to create a report. Via the cpp code or via the designer. In the app is a form with MaskEdits what presents the customer/client query.

Is it possible to get these MaskEdits text into the designer page?

And what about a RichEdit component?

P.

procedure PageHeader2OnBeforePrint(Sender: TfrxComponent);
var S: String;                  
begin
 S := 'Inhalt';                  
 Engine.AddAnchor(S);  
end;

But in the preview I get an error:

undefined identifier: 'Inhalt'

What is the solution?

frxReport1.Page.UnlimitedWidth := True;

Is this property supported in Lazarus, and if not, how can it be achieved if you want to achieve such an effect?

The function works just like in Excel: regardless of the number of columns, if you define the paper size as A4, it will display according to A4 dimensions. Any columns that don't fit will be moved to the next page.

Is there a way to use TfrxRichView in a multi-threaded server app?

What code should I use if I want the same functionality as the default "insert text" button, that makes a memo appear under the mouse cursor and can be placed manually?

with regards,

Martijn

Is there any option or script to change color just a parte of string inside a memo ?

Ex.: my meno10 = 'Hello world'. I want to change the word "world" to blue (clBlue), just that word.

of course it's a meno with database field. Can i add some script or change something beforeprint ?

thx for all

I can have a name column and one price column, but I can also have a name column and multiple price columns.

I know I can use a PivotTable object for this, but it requires appropriate data preparation.

I can't make any modifications in the program, so I'd like to do everything in FR Designer.

However, when using XLSX export, Delphi throws the following error at the Report.Export(frxExport) line where frxExport is a TFrxXLSExport control:-

"34ee" is not a floating point value

It seems that FastReports is unable to export the report as-is but is attempting to convert values, which causes it to fail at characters it does not like.

Is there a problem with exporting XLSX formats?

Note: I am attempting to export the attached report. If it is a more complicated report with many numbers, the program crashes instead with an AV at the export event.

procedure Rich1OnBeforePrint(Sender: TfrxComponent);

var

 Stm: TMemoryStream;

begin

  Stm := TMemoryStream.Create;

//  Stm.Write('TESTE GERAL', Length('TESTE GERAL'));        

//  Stm.Write(<VRDIDS>, Length(<VRDIDS>));

//  Stm.Write(PChar(<VRDIDS>)^, Length(<VRDIDS>));

//  Stm.Position:= 0;

//  Rich1.RichEdit.Lines.LoadFromStream(Stm);

  Rich1.AllowExpressions:= false;          

  Rich1.RichEdit.Lines.Text:= '''' + <VRDIDS> + '''' ;

  //Rich1.RichEdit.Lines.Text:= (<VRDIDS>);

end;

Thank you all

I have a TFrxWPtoolview component that's a descendant of TFrxStretchable.
I'm unsure what my DrawPart function should return.
According to the FastReport comments included in the source, the view's drawPart is called
in the TfrxEngine.SplitObjects function, and just before your comment, it says:
{ trying to place it }
{ DrawPart method returns the amount of unused space. If the view
can't fit in the height, this method returns the Height }
1 er com.
I don't understand, this is the first part of the TFrxStretchable
(CalcHeight has already been called and FR knows that it doesn't fit in height) 
so DrawPart expects the preparation of the drawing of the 1st part,
I have a case where DrawPart returns 130 px (the view is 200 my text is 70 px),
but on the 1st draw, FR offers me a Height of 200 (FY1 - FY) whereas it should be 70
2nd com.
"Return the height, "
What height? That of the first part or the whole thing?

I have problems where the report just blows up all over the place for some people for fields that don't exist.

We have about 2000+ customer servers out there and out of my control, the database end is a bit... volatile.

But in report land, never really been an issue.

Well since 2025.1.5 it seems when I save any of my reports it creates <FieldDefs> section, which does NOT happen in the older version.

If i delete these out of the file in notepad, for the customer, things work fine.

If i open the file in FR designer and resave. It all comes back again.

I thought it was related to the "Auto Update Fields" vs "User Field Definitions" but that doesn't seem to change anything? ZERO clue what these do then...

I can't find anything about this in the manuals page.

So, question is, how the heck do I disable this feature? Or do I need to just remove this my self always going forward every time i make changes?

is it possible to enable or disable from Delphi program?

Thank you for help,

Brigitte

 procedure frxReportBeforePrint (Sender: TfrxReportComponent);

If Sender.Name = <name of TfrxHTMLView object>

  then TfrxHTMLView (Sender).HtmlViewer.Text: = InhaltHTML;

 At runtime I get an error message (access violation at ... read of address ...). The error message occurs with the Vcl.Graphics function TFont.GetSize.

The HTML string can be displayed in a TWebBrowser component without errors.

What is wrong? Are there other ways to assign data to a TfrxHTMLView object at runtime? I am using the FastReport VCL 2021.3.1 version. 

According to available information, limitations of demo version are:

• a watermark on each page
• a maximum of 5 pages

Are there any other limitations?

Best regards,

Venancio Lasquibar
